Abstract (en)
A hybrid-electric propulsion system 50 for an aircraft 10 includes a turbomachine 102, the turbomachine 102 including a first spool 124 and a second spool 122. A method 400 of operating the hybrid-electric propulsion system includes operating at 402, by one or more computing devices, the turbomachine such that the first spool mechanically drives a prime propulsor of the hybrid-electric propulsion system; and modifying at 404, by the one or more computing devices, a speed relationship parameter defined between the first spool and second spool by providing electrical power to, or drawing electrical power from, an electric machine mechanically coupled to the first spool, the second spool, or both.
